Dithiothreitol solution is an aqueous solution of dithiothreitol (DTT) (CAS No.: 3483-12-3). The product is used in medical diagnostics, histology and scientific laboratories. It is particularly useful for reducing disulfide bonds in proteins and stabilizing enzymes.

The chemical name of DTT is 1,4-dithiothreitol or threo-2,3-dihydroxy-1,4-dithiolbutane, and its molecular formula is C4H10O2S2. In aqueous solution, DTT reacts with disulfide bonds to reduce them and form two free thiol groups. In the process, the sulfur-containing disulfide bonds are converted to thiols, which enables the reduction process and affects the properties of the protein or enzyme involved.

DTT solutions are widely used to elucidate protein structures or to reduce the disulfide bonds in biological samples to study their function or interaction with other biomolecules. For example, by reducing disulfide bonds, protein structures can be deciphered, protein complexes can be stabilized, or enzyme reactions can be slowed down.

In summary, dithiothreitol solution, aqueous is primarily used to reduce disulfide bonds in proteins and stabilize enzymes.
